MasoSine speeds condensed milk pumping for Kerry12 December 2012

Kerry Ingredients & Flavours' Tenbury Wells plant is reporting success with a MasoSine SPS 2.5 sine pump handling viscosity and flow challenges with condensed milk in toffees sauce production.

Process manager Charles Bishop-Miller says that the pump's sinusoidal rotor has overcome the limitations of a rotary lobe pump and is enabling powerful suction with low shear, low pulsation and gentle handling.

Bishop-Miller explains that introducing the new toffee sauce to 10 production lines led to pumping problems as soon as demand grew beyond anything that could be handled by manual labour.

"As luck would have it we already had a MasoSine SPS 2 on trial for another, completely different application," he says. "It was being used for a thinner liquid stream that was also sometimes thick.

"Having seen the light work it made of transferring condensed milk, I believe it could handle almost anything we throw at it."

Bishop-Miller makes the point that in his experience that rotary lobe pumps fail to provide enough suction to perform priming operations. Further, the handling capability of lobe pumps can be quite harsh, offering uneven flows.

"Ultimately, we estimate the sine pump offers 20% faster pumping times than a lobe pump. It has also allowed us to redeploy the manual labour resource to a more value-added role," he says.

"Greater versatility, self-priming ability and ease-of-cleaning also stack in favour of the MasoSine pump. In terms of the latter, we can remove the front and be hosing out in a matter of minutes."
